[Bug debug/49901] gfortran.dg/debug/[pr35154-dwarf2.f/pr37738.f] failures on darwin

fix PR49901

The output from the tests is a little misleading.

These tests also set other flags in addition to those listed; including
-gno-strict-dwarf  ... 
... which exposes the Darwin back-end to the new .debug_macro section, for
which it has no suitable section description.

Choices; 
1) skip the tests on Darwin.
2) provide the section - although that doesn't imply that the remainder of the
tool-chain will do anything useful with it.

Here's an untested patch for choice 2.
